3 A PCMCIA ethernet driver for Asix AX88190-based cards
4
5 The Asix AX88190 is a NS8390-derived chipset with a few nasty
6 idiosyncracies that make it very inconvenient to support with a
7 standard 8390 driver. This driver is based on pcnet_cs, with the
8 tweaked 8390 code grafted on the end. Much of what I did was to
9 clean up and update a similar driver supplied by Asix, which was
10 adapted by William Lee, william@asix.com.tw.

763 This is the chip-specific code for many 8390-based ethernet adaptors.
764 This is not a complete driver, it must be combined with board-specific
765 code such as ne.c, wd.c, 3c503.c, etc.
766
767 Seeing how at least eight drivers use this code, (not counting the
768 PCMCIA ones either) it is easy to break some card by what seems like
769 a simple innocent change. Please contact me or Donald if you think
770 you have found something that needs changing. -- PG
771
772 Changelog:
773
774 Paul Gortmaker : remove set_bit lock, other cleanups.
775 Paul Gortmaker : add ei_get_8390_hdr() so we can pass skb's to
776 ei_block_input() for eth_io_copy_and_sum().
777 Paul Gortmaker : exchange static int ei_pingpong for a #define,
778 also add better Tx error handling.
779 Paul Gortmaker : rewrite Rx overrun handling as per NS specs.
780 Alexey Kuznetsov : use the 8390's six bit hash multicast filter.
781 Paul Gortmaker : tweak ANK's above multicast changes a bit.
782 Paul Gortmaker : update packet statistics for v2.1.x
783 Alan Cox : support arbitrary stupid port mappings on the
784 68K Macintosh. Support >16bit I/O spaces
785 Paul Gortmaker : add kmod support for auto-loading of the 8390
786 module by all drivers that require it.
787 Alan Cox : Spinlocking work, added 'BUG_83C690'
788 Paul Gortmaker : Separate out Tx timeout code from Tx path.

843 * SMP and the 8390 setup.
844 *
845 * The 8390 isn't exactly designed to be multithreaded on RX/TX. There is
846 * a page register that controls bank and packet buffer access. We guard
847 * this with ei_local->page_lock. Nobody should assume or set the page other
848 * than zero when the lock is not held. Lock holders must restore page 0
849 * before unlocking. Even pure readers must take the lock to protect in
850 * page 0.
851 *
852 * To make life difficult the chip can also be very slow. We therefore can't
853 * just use spinlocks. For the longer lockups we disable the irq the device
854 * sits on and hold the lock. We must hold the lock because there is a dual
855 * processor case other than interrupts (get stats/set multicast list in
856 * parallel with each other and transmit).
857 *
858 * Note: in theory we can just disable the irq on the card _but_ there is
859 * a latency on SMP irq delivery. So we can easily go "disable irq" "sync irqs"
860 * enter lock, take the queued irq. So we waddle instead of flying.
861 *
862 * Finally by special arrangement for the purpose of being generally
863 * annoying the transmit function is called bh atomic. That places
864 * restrictions on the user context callers as disable_irq won't save
865 * them.

3 A PCMCIA ethernet driver for NS8390-based cards
4
5 This driver supports the D-Link DE-650 and Linksys EthernetCard
6 cards, the newer D-Link and Linksys combo cards, Accton EN2212
7 cards, the RPTI EP400, and the PreMax PE-200 in non-shared-memory
8 mode, and the IBM Credit Card Adapter, the NE4100, the Thomas
9 Conrad ethernet card, and the Kingston KNE-PCM/x in shared-memory
10 mode. It will also handle the Socket EA card in either mode.
